Title: Tetningssammenstilling
Inventor: LUNDHEIM LARS TIMBERLID
IPC: E21B33/128
Filed: 2013-01-29
Abstract: Tetningssammenstilling med en tetningsring (3) som tetter mellom et indre rørformet element (105) med en ytre flate (5) og et koaksialt anordnet ytre rørformet element (107) med en indre flate (7). Den indre eller ytre flaten har en skråstilt elementflate (9) mot hvilken tetningsringen (3) glir når den beveger seg i aksial retning, og således endrer sin omkrets (C). En aktiveringsanordning (2) påfører en aktueringskraft på tetningsringen og presser en skråstilt tetningsringflate (11) til tetningsringen (3) mot den skråstilte elementflaten (9). Aktiveringsanordningen (2) bibeholder nevnte aktueringskraft langs en funksjonsbane til tetningsringen. Som et resultat av radiell ekspansjon eller radiell reduksjon av den indre flaten (7) eller den ytre flaten (5), hvilken enn som er motsatt av den skråstilte elementflaten, i et tilfelle hvor den radielle avstanden mellom den indre og ytre flaten øker, beveger aktiveringsanordningen tetningsringen (3) langs den skråstilte elementflaten (9) i en første retning, og øker forskjellen mellom omkretsen (C) til tetningsringen og den originale omkretsen (CO) til tetningsringen; i et tilfelle hvor den radiale avstanden mellom den indre og ytre flaten minker, blir aktiveringsanordningen (2) komprimert av tetningsringen som blir presset mot den skråstilte elementflaten (9) av kraft fra den indre eller ytre flaten, som resulterer i en bevegelse av tetningsringen langs den skråstilte elementflaten i en andre retning som er motsatt av første retning. Forskjellen mellom omkretsen (C) til tetningsringen (3) og den originale omkretsen (CO) til tetningsringen (3) blir da redusert.

Title: Method of normalizing internally reinforced converte by removal of chlorides
Inventor: VENNESLAND OYSTEIN
IPC: B28B11/00
Filed: 1990-05-16
Abstract: A process for rehabilitation of internally reinforced concrete which comprises the temporary application of an adherent coating of an electrolytic material (12) to surface areas of the concrete. Distributed electrode (13) means, preferably a wire grid, is embedded in the adherent coating. Voltage sufficient to develop a current of about 1-5 amps/m<2> is applied between the reinforcement and the distributed electrode, to cause migration of chloride ions from the concrete into the electrolytic coating. A highly preferred material for the adherent electrolytic layer is cellulosic pulp, premixed with water or other solution (such as calcium hydroxide) in a nozzle and sprayed onto the surface of the area being treated. Desirably, the distributed electrode is formed of a ferrous material reactive with chlorine, to minimize the release of free chlorine gas into the ambient. Particularly for tensioned reinforcement, the process monitors polarization of the tensioned steel to prevent hydrogen embrittlement.
